MCU Phase 4: Every Single Character Confirmed (So Far)

19. Nebula (Karen Gillan) - What If?

While we don't yet know if she's got a part to play in the third Guardians movie (it's probably very likely) the angriest of the Guardians returns for What If...? and presumably the same story as Thanos. Or perhaps the story of why T'Challa ends up being Star-Lord. Honestly, the mind boggles a little, but it's just great that we get to have the original actors voicing their characters in animated form.

Seeing what Nebula would have been like if Thanos hadn't turned her into a living monument to his evil would be an interesting angle, if that's the sort of thing What If...? looks to explore.
